Description

Die Erfindung betrifft eine Vorrichtung zur Kraft- und Bewegungsübertragung gemäß dem Oberbegriff fes Anspruchs 1.The invention relates to a device for transmitting force and movement according to the preamble fes claim. 1

Bei einer bekannten Vorrichtung dieser Art wird das Gelenklager, an dem die Stange bzw. Gelenkstange befestigt ist, mittels einer Übermaßpassung zwischen dem Lagerinnenring und dem Bolzen auf diesem fixiert. Die Übermaßpassung sorgt für eine feste, spielfreie Verbindung des Lagerinnenringes mit dem Bolzen. Außerdem ergibt sich eine Verdrehsicherung zwischen beiden Elementen. Die Drehbewegung findet so zwingend im Gelenklager selbst statt. Nachteilig bei dieser Vorrichtung ist vor allem die kraftaufwändige Montage bzw. Demontage, die ohne Spezialwerkzeuge kaum zu bewerkstelligen ist. Darüber hinaus können wegen der Übermaßpassung und der damit verbundenen erheblichen Reibung bei der Montage bzw. Demontage Beschädigungen und Verschleißerscheinungen auftreten. Insbesondere bei Vorrichtungen, die justiert werden müssen und zu diesem Zweck unter Umständen mehrmals montiert und demontiert werden müssen, entstehen dadurch erhebliche Probleme. Auch bei sicherheitskritischen Einrichtungen oder aufgrund der betrieblichen Belastung besonders verschleißanfälligen Einrichtungen, bei denen regelmäßig Wartungsarbeiten durchgeführt werden müssen, erweist sich die schwierige Montage bzw. Demontage als sehr nachteilig.In a known device of this type, the spherical plain bearing, on which the rod or articulated rod is attached, fixed by means of an interference fit between the bearing inner ring and the bolt on this. The interference fit ensures a firm, backlash-free connection of the bearing inner ring with the bolt. In addition, there is an anti-rotation between the two elements. The rotational movement takes place so necessarily in the joint bearing itself. The disadvantage of this device is especially the power-consuming assembly and disassembly, which can hardly be accomplished without special tools. In addition, due to the interference fit and the associated considerable friction during assembly or disassembly damage and signs of wear may occur. In particular, in devices that need to be adjusted and may need to be mounted and dismantled several times for this purpose may cause significant problems. Even with safety-critical facilities or due to the operational burden particularly susceptible to wear equipment in which regular maintenance must be performed, the difficult assembly or disassembly proves to be very disadvantageous.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art anzugeben, die sich durch erheblich leichtere Montierbarkeit bzw. Demontierbarkeit auszeichnet.The invention has for its object to provide a device of the generic type, which is characterized by considerably easier mountability and disassembly.

Die Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch die leichte Untermaßpassung zwischen Lagerinnenring und Bolzen lässt sich das Gelenklager problemlos und ohne Werkzeug auf den Bolzen aufschieben. Die notwendige kraftschlüssige Verbindung zwischen Lagerinnenring und Bolzen wird durch einen Federring hergestellt, der in eine umlaufende Nut in der Mantelperipherie des Bolzens einsetzbar ist. Die Nut befindet sich vorzugsweise etwa in der Mitte des Lagersitzes. Die Nuttiefe ist derart zu wählen, dass sich das Gelenklager mit der Hand oder mit leichten Schlägen über den Federring treiben lässt. Auf diese Weise wird eine feste Verbindung zwischen Lagerinnenring und Bolzen erreicht, wodurch ein Mitdrehen des Lagerinnenringes auf den Bolzen verhindert wird. Nur das Gelenklager selbst, beispielsweise ein Kugellager, gestattet ein Schwenken oder Drehen der Gelenkstange um die Längsachse des Bolzens.The object is achieved with the characterizing features of claim 1. Due to the slight undersize fit between the bearing inner ring and the bolt, the spherical plain bearing can easily be pushed onto the bolt without tools. The necessary frictional connection between the bearing inner ring and the bolt is made by a spring ring, which is insertable into a circumferential groove in the mantle periphery of the bolt. The groove is preferably located approximately in the middle of the bearing seat. The groove depth should be selected so that the joint bearing can be driven by hand or with light strokes over the spring washer. In this way, a firm connection between the bearing inner ring and bolt is achieved, whereby co-rotation of the bearing inner ring is prevented on the bolt. Only the pivot bearing itself, such as a ball bearing, allows pivoting or rotation of the pivot rod about the longitudinal axis of the bolt.

Bei Justierarbeiten ergibt sich darüber hinaus der Vorteil, dass der Federring während der Justierarbeiten noch nicht eingesetzt werden muss, so dass mehrfaches Abnehmen und Wiederaufsetzen des Gelenklagers auf dem Bolzen für Justierzwecke ohne jegliche Kraftanstrengung möglich ist. Erst nach Abschluss der Justierarbeiten, quasi bei der endgültigen Montage, wird der Federring eingesetzt, um eine verdrehsichere Befestigung des Gelenklagers auf den Bolzen sicherzustellen.When adjusting results in addition to the advantage that the spring ring during adjustment does not need to be used so that multiple removal and replacement of the pivot bearing on the bolt for adjustment purposes without any effort is possible. Only after completion of the adjustment work, virtually in the final assembly, the spring ring is used to ensure a rotationally secure attachment of the hinge bearing on the bolt.

Gemäß Anspruch 2 sind zur Fixierung des Gelenklagers auf den Bolzen in axialer Bolzenrichtung ein Distanzring und ein Federstecker vorgesehen. Der Federstecker ist nach Art einer Haarklemme geformt, wobei ein Schenkel durch eine radiale Bohrung am Bolzenende hindurch geschoben wird und der andere Schenkel das Bolzenende auf einem Teil des Umfangs formschlüssig federnd umschließt. Dadurch ist ein unbeabsichtigtes Herausziehen oder Herausrutschen des Federsteckers verhindert. Ein Griffende ermöglicht dennoch eine leichte Montage bzw. Demontage des Federsteckers.According to claim 2, a spacer ring and a spring pin are provided for fixing the hinge bearing on the bolt in the axial direction of the bolt. The spring connector is shaped in the manner of a hair clip, wherein a leg is pushed through a radial bore at the bolt end and the other leg surrounds the bolt end on a part of the circumference form-fitting resiliently. This is an unintentional Pulling out or slipping out of the spring plug prevented. A grip end still allows easy assembly and disassembly of the spring connector.

Vorzugsweise ist gemäß Anspruch 3 eine Verwendung der Vorrichtung zur Kraft- und Bewegungsübertragung bei Weichenstellsystemen vorgesehen. Denkbar sind jedoch auch diverse andere Einsatzmöglichkeiten, bei denen es auf leichte Montier- bzw. Demontierbarkeit eines Lagers auf einen Bolzen ankommt.Preferably, according to claim 3, a use of the device for force and motion transmission is provided in point setting systems. Conceivable, however, are also various other uses, where it depends on easy mounting or dismounting a bearing on a bolt.

The invention will be explained in more detail with reference to figurative representations. Show it
FIG. 1
the main components of a condyle attachment and
FIG. 2
the assemblies of Figure 1 in the assembled state.

Eine Stange, beispielsweise Gelenkstange 1 für ein Weichenstellsystem, soll um eine im Wesentlichen senkrecht zur Längsachse 2 der Gelenkstange 1 ausgerichtete Achse 3 um einen bestimmten Winkel schwenkbar oder um 360° drehbar gelagert werden. Dazu ist ein Gelenklager 4 vorgesehen, welches einerseits mit der Gelenkstange 1 fest verbunden ist und andererseits an einem zur Achse 3 fluchtenden Bolzen 5 fixiert ist. Das Gelenklager 4 ist mit nicht dargestellten Lagerelementen, beispielsweise nach Art eines Kugellagers, ausgestattet, wodurch die Schwenk- oder Drehbewegung der Gelenkstange 1 ermöglicht wird. Ein Lagerinnenring 6 verschließt das Lagergehäuse innenseitig und dient der festen Verbindung mit den Bolzen 5. Zwischen Lagerinnenring 6 und Bolzen 5 ist eine leichte Untermaßpassung vorgesehen. Dadurch lässt sich das Gelenklager 4 samt Gelenkstange 1 leicht auf den Bolzen 5 aufschieben. Damit eine drehsichere Verbindung zwischen Lagerinnenring 6 und Bolzen 5 entsteht, ist der Bolzen 5 mit einer umlaufenden Nut 7 versehen, in die ein Federring 8 eingesetzt wird. Die Bemaßung von Nut 7 und Federring 8 ist dabei derart getroffen, dass sich der Lagerinnenring 6 immer noch relativ leicht auf den Bolzen 5 aufschieben lässt, aber dennoch eine ausreichende Klemmung zwecks Verdrehsicherung entsteht.A rod, for example, articulated rod 1 for a points system, is to be mounted pivotable about a certain angle 3 or substantially perpendicular to the longitudinal axis 2 of the articulated rod 1 axis 3 by a certain angle or 360 °. For this purpose, a joint bearing 4 is provided, which is firmly connected on the one hand with the hinge rod 1 and on the other hand is fixed to a pin 3 aligned with the axis 3 bolt. The joint bearing 4 is equipped with bearing elements, not shown, for example, in the manner of a ball bearing, equipped, whereby the pivoting or rotational movement of the joint rod 1 is made possible. A bearing inner ring 6 closes the bearing housing on the inside and serves the firm connection with the bolt 5. Between bearing inner ring 6 and pin 5 a slight undersize fit is provided. As a result, the joint bearing 4 together with the joint rod 1 can be easily pushed onto the bolt 5. So that a rotationally secure connection between the bearing inner ring 6 and bolt 5 is formed, the bolt 5 is provided with a circumferential groove 7, in which a spring ring 8 is used. The dimensioning of groove 7 and spring ring 8 is made such that the bearing inner ring 6 can still postpone relatively easily on the bolt 5, but still sufficient clamping for the purpose of rotation is created.

Ein Distanzring 9 und ein Federstecker 10 am Bolzenende sorgen für die axiale Lagefixierung des Gelenklagers 4 auf den Bolzen 5. Der Federstecker 10 wird mit einem Schenkel durch Bohrungen 11 am Bolzenende gesteckt und mit einem zweiten Schenkel klemmend über das Bolzenende geschoben, wie Figur 2 zeigt. Zur leichten Montage und Demontage ist der Federstecker 10 mit einem ösenartigen Griffende versehen.A spacer ring 9 and a spring pin 10 at the bolt end provide for the axial positional fixation of the joint bearing 4 on the bolt 5. The spring connector 10 is inserted with a leg through holes 11 at the bolt end and pushed with a second leg by clamping over the bolt end, as Figure 2 shows , For easy assembly and disassembly of the spring connector 10 is provided with a loop-like grip end.

Durch die Untermaßpassung zwischen Lagerinnenring 6 und Bolzen 5 und die Klemmung mittels des Federringes 8 ist bei abgezogenem Federstecker 10 das Gelenklager 4 mit der Gelenkstange 1 ohne große Kraftanstrengung und ohne besonderes Werkzeug auf den Bolzen 5 aufschiebbar bzw. von den Bolzen 5 abziehbar.By Untermaßpassung between bearing inner ring 6 and pin 5 and the clamping by means of the spring ring 8 is withdrawn spring pin 10, the joint bearing 4 with the hinge rod 1 without great effort and without special tools on the bolt 5 pushed or deducted from the bolt 5.

Die Erfindung beschränkt sich nicht auf das vorstehend angegebene Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, welche auch bei grundsätzlich anders gearteter Ausführung von den Merkmalen der Erfindung Gebrauch machen.The invention is not limited to the embodiment given above. Rather, a number of variants are conceivable, which make use of the features of the invention even with fundamentally different type of execution.
